“…show that there are two prominent peaks: the first spectrum contains at 2θ = 20.09 0 , which corresponds to the crystallography phase of cellulose-I, and the second at 2θ = 16.01 o , which corresponds to the presence of amorphous cellulose IV; both peaks exhibit monoclinic structures. These peaks are more noticeable when amorphous materials are present (Habibunnisa et al, 2022). The size of the coconut dregs crystal obtained from XRD observations is 11.8 nm.…”

Agricultural waste, including coconut pulp, contains lignocellulose and is a very important, renewable and sustainable industrial raw material. Many of the food, textile, pharmaceutical, paint and resin, agrochemical, oil processing, and other sectors utilize lignocellulosic derivatives. The objectives of this study were to determine the availability of coconut pulp in Padang City-West Sumatra, analyse the lignocellulosic components contained and cell surface morphology, and observe the chemical elements in coconut pulp waste. An exploratory approach was used in this study to achieve these objectives. The results showed that there were 98 coconut milk entrepreneurs spread across traditional markets in Padang City, West Sumatra. Every day the coconut milk squeeze business examined produces ± 1.18 tonnes of coconut pulp. Coconut waste also contains 47.18% cellulose, 10.58% lignin, and 12.10% hemicellulose. Based on the XRD results, the crystal size of coconut pulp obtained from XRD observation is 11.8 nm.

The study explores how dyes can improve the strength and optical properties of composites made from flax seed fiber and epoxy, which are incorporated with biosynthesised TiO2 nanoparticles derived from the Curcuma longa plant. The TiO2 nanoparticles were produced using a synthesis method that involved curcumin from Curcuma longa as a reducing and stabilizing agent. By introducing dyes to these composites, it enhances the bonding between layers. Optimizes their ability to absorb UV light. The research findings analyze how the ILSS (interlaminar shear strength) improves by adding natural dye additives and measurable enhancements in their optical characteristics. The results indicate that composite materials containing 5 wt% of nanoTiO2 exhibit the ILSS value (52.31 MPa). This is because the TiO2 particles are evenly distributed throughout the substance at this concentration. The crystal orientation and size (71.02 nm) of biosynthesized TiO2 nanoparticles were determined using X-ray diffraction techniques. Regarding optical properties, observations were made across a wavelength range of 450–2300 nm. Compared to a surface, it was observed that incorporating dyes into adsorbents led to increased absorption and reduced transparency across light wavelengths. This study offers insights into the uses of composites infused with natural dyes in sustainable engineering and materials that protect against sunlight.

Natural seed fiber reinforced composite materials are replacing many conventional ones because of their excellent properties, less weight, easy availability, etc. Composite materials are used in many areas because of their superior features. Mechanical property is one of the vital parameters for choosing the material. The current investigation has revealed an importance of recently well-known Wrightia tinctoria nano seed fibers (WTNSFs), which are extracted physically. Wrightia tinctoria nano seed fiber reinforced composite was prepared with the epoxy resin by hand layup method. Epoxy resin is easy to handle and available at low cost. Mechanical tests are conducted reinforced composites of plain epoxy and WTNSFs to obtain strength properties like tensile, flexural, impact. Water absorption tests also performed on composites. Here, the developed composites are easy to handle, offered economically, and used primarily in marine applications due to less water absorption and good wax content. A comprehensive description of different tests and the properties of WTNSFs are studied and compared with the other existing natural fibers. This work showed that 35% combination of WTNSFs reinforced epoxy matrix offers enhanced mechanical properties with minimum water absorption compared with plain epoxy composites.
